Moloch was Satan. Nimrod and Semiramis worshipped Moloch. Babies were sacrificed to Moloch around the time of Christmas. Priest of Moloch would rape virgins around the Spring Equinox so their babies could be killed around Christmas.

Nimrod became Marduk or Baal
Semiramis became Ishtar pronounced Easter and Easter was celebrated by the Pagans
Tammuz was the incarnate God, or Nimrod reborn by immaculate conception. However, His birth probably due to adultery.

That was the story Semiramis told Her populous. Tammuz was killed by a pig whilst hunting and Semiramis declared a forty day period of weeping prior to Easter, known in Ezekiel as the 'weeping of Tammuz'

The RCC made this known as Lent.
